Abstract

Official abstract text for this publication.

A method utilizes cluster-awareness to effectively support a live partition mobility (LPM) event and provide recovery from node failure within a Virtual Input/Output (I/O) Server (VIOS) cluster. An LPM utility creates a monitoring thread on a first VIOS on initiation of a corresponding LPM event. The monitoring thread tracks a status of an LPM and records status information in the mobility table of a database. The LPM utility creates other monitoring threads on other VIOSes running on the (same) source server. If the first VIOS VIOS sustains one of multiple failures, the LPM utility provides notification to other functioning nodes/VIOSes. The LPM utility enables a functioning monitoring thread to update the LPM status. In particular, a last monitoring thread may perform cleanup/update operations within the database based on an indication that there are nodes on the first server that are in failed state.

First claim

Opening claim text (preview).

What is claimed is: 1. In a cluster-aware data processing system having a processor, a memory coupled to the processor, at least one input/output (I/O) adapter that enables connection to an external network with a shared storage repository, and a plurality of virtual I/O servers (VIOSes) that form a VIOS cluster with a shared database, where each VIOS is cluster aware, a method comprising: activating a first monitoring thread on a first VIOS of one or more VIOSes of a first server…
